IMPROVEMENT IN SHINGLE-MAGHINES.

lO ALL WIIOM I'l MAY CONCEIIN:

Be it known that I, DAVID L. PEACOCK, of Rockport, in the county ofSpencer, and State of Indiana, have inx-'ented a new'anll improvedShingle-Machinc; and I do hereby declare the following to `be a full,clear, and

exact description of thesame, reference being had to the accompanyingdrawings, forming part of this specification, and in which- Figure 1represents a perspectiveview of the cutter-frame M.

Figure 2 is a front elevation of my invention.

Figure 3A is a rear elevation of the same.'

Figure 4 is a longitudinal vertical section of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

In this inventionthe shingle is split from a block, and planed whilepassing through the machine.

In order that others skilled in the 'art to-which my inventionappertains may be enabled vto make and use the same, I will-"proceed todescribe it in detail.

i In the drawings, A A represent the bed-pieces, B B the posts or legs,C C the frame, and D D the boxes in which the shingle-bolts are heldwhile Athe shingles are being out from them. E is a shaft, bearing oneach end a pulley, e', from which a. belt works the lower planer bymeans of the pulleyf. F is' the. lower planer, provided with knives, aa, and running in fixed boxes inthe frame C. The upper planer Gr runs inbearings in the end of two arms, H H, p ivoted to the frame C at 7L, andcapable of rising and falling with the arms H H. The latter carry varoller, I, just behind the planer Gr, bearingl in boxes which have avertical sliding motion in slots in the arms H H. Theshaft of the planerG has a pulley, g, on each end, to which motion is communicated by a.crossed belt from the lower planer-shaft. b is a screen in front of theupper planer G. .lust beneath it, and in front of the upper planer, isroller, K, similar in construction to the roller I, working also inboxes having n. vertical sliding motion in slots in'the inside of theframe C. i The inner sides of the frame C are each provided with twoparallel longitudinal grooves or channels, L L, which support and guidethe sliding cutter-frame M. The latter is composed of two plates, mandm', attached together by the blocks m, to which they are bolted. In anaperture in the upperplate m the cutting-knife K is ixed-a knifestraight on its upper and bevelled on its under side. The upper side ofthe plate m, in frontof the cutting-knife N, is cut down,so that thebolt resting upon it will come in contact with the edge of the knife.The under plate m has a. raised bed, `m/, upon which the shingle fallsafter` being cut from the bolt. lThe forward end of the under plateterminates in two arms, tt, projecting forward at each side, andbevellediidown to a sharp edge, the purpose of which is to run under theends ofthe arms H H, which have their lower corners slightly bevelledoff, to insurethe sliding of the plate m under them, whereby the planerG is gradually raised as the cutter-frame M advances towards it. O is abeam, whichjust grazes the upper surface of the bed m as thecutter-frame is slid forward and back in its guiding-grooves. P is a atoor in front of the planers, extending about to the middle ofthemachine. The plate m slides back and forth upon this floor, its forwardend, between the arms that push up the planer, as before described,being cut square, as shown at r, so as to push along whatever may belying upon the tl'oor I as the cutter-frame advances.

The operation of a. machine thus constructed is as follows: The bolt isplaced in the box D, its side down. The cutter-frame is then adjusted inthe grooves L L and slid forward, when the. knife N comes in Contactwith lthe lower side of the bolt and cuts or splits a shingle therefrom,which is forced lthrough the'aperture in front of the knife N, and fallsupon the raised bed m in the lower plate of the cutter-frame.The'cutter-frame is then drawn back for a new cut, the beam O preventingthe shingle from being carried back with it, and sliding the shingleforward upon the fra-me until it drops oil' of the bed m" upon the plateat mm. By this time a new shingle has fallen upon the bed yn", which inits turn pushes the first shingle forward entirely off of the slidingframe upon the floor P. As the frame is again drawn back and forth, athird shingle falls upon the bed m", and, in connection with the secondshingle, pushes the first shingle between the planers. The shoulders`rand r assist the rear shingles in pushing the forward ones towards theplaners. The bed mm, the part mm', and the loor P in front of theshoulder r, when the sliding frame is drawn back, must each carry oneshingle forward endways. The arms upon the forward end of the plate mmust be bevelled just so much as is necessary in order to cause theplaner G to give the proper bevel to'the shingle.

I do not broadly claim a. slidipgueutter-frame, holding a. knife, andoperating in connection with a box holding t'ne bolts; but i What I doclaim as my invention, and desire to secure by Letters Patent., is-

1. A cutter-frame, composed of two parallel plates m m', the upper oneholding a knife, N, and the lower one having a. raised bed, m", arrangedand combined substantially as and for the purpose speeied.

2. The combination of a. cutter-frame,`l1aving tapering arms tt, withthe movable planer G, bearing in hinged arms H H, substantially as andfor the purpose specified.
